Investigating the Effectiveness of an Interactive IRF-Based English Grammar Learning System

Chien-Yuan Su


Computer-supported language learning has the potential to promote relevant work in support of instant, interactive language discourse that fulfils educational purposes and fosters individual language learning. This study presents an interactive IRF-based English grammar learning assistant system (EGLA) that aims to improve students’ grammatical knowledge and correct their grammar errors and misspellings if they have any. A quasi-experimental design is adopted to examine its effects on an English grammar achievement test for three classes of junior high school students. These three classes were assigned to the experimental group and control groups A and B. The experimental group used EGLA that harnessed IRF moves, control group A used EGLA but without IRF moves, whereas control group B received an IRF-based English grammar discourse from an English tutor in the classroom. The results demonstrated that the experimental group was significantly better than control group A, but was not significantly different from control group B. The results are discussed, and directions for further investigation are provided.
